I'm in Virginia. I bought my motor from a fellow member here (348nut) back in 2004. The motor was in tack, complete from carb to exhaust manifolds. The motor supposely was from the factory in a '61 convertibile, dropped a valve and destoryed one cylinder. It was rebuilt using low compression pistons and a hyd. cam, basicly used 250 horse 348 stuff to rebuild the motor. It was then installed in a logging truck and ran for years until the old truck was junked. The member here that I bought it from bought the motor as scrap thinking it was a 348. He later cleaned the motor and discovered the 623 casting number, got to looking and found out he had a complete '61 409 motor, when I disassembled it we found exactly what he had told me to be true, it had a sleeve in the # 8 cylinder but otherwise was standard bore. Of course i had it rebuilt back to the '09 spec. At the time I didn't have a body to put it in but knew of a documented '61SS body that had no motor so I bought it and put the two together. As for what Grumpy said about the 409's in NASCAR, I don't know about them selling the motors to the drag racers, they ran well on the short tracks, just didn't do too well on the speedways, Ned Jarrett won the Championship in '61 so they didn't do bad but they could have been running the 348 becasue from just looking at the motor you couldn't have told the difference. One thing I noticed from the photo of your car, it appears you have the fuel line going into the carb from the front, I beleive that was correct for the very early motors, mine has the original carb and the fuel line enters from the rear like the 380 horse '62's. Wish we weren't so far apart, be great to have these two cars together at the same show, '61 409's from both ends of the specturm, a Fleetmaster to a Super Sport, maybe we'll meet up somewhere.
